In Grodno Zoo, all exits to outdoor enclosures are necessarily closed at night during winter so that the animals do not freeze. But the jaguar Mr. Black is a truly mischievous fellow who doesn't like restrictions and prefers free walks between the outdoor and indoor areas.

Every evening, zoo staff are forced to specially encourage the jaguar to spend the night indoors.
For this, they use his favorite treat — a chicken egg.
Black knows perfectly well that as soon as he enters the enclosure for the treat, the shutter will immediately close, but he can't help himself — the craving for the treat overcomes everything.
